West Valley math teacher charged with assault on a minor

A Phoenix math teacher has been arrested, accused of assaulting a woman and her 14-year-old daughter.

The teacher, identified as Ryan Nicholas Prassas, is facing charges of aggravated assault on a minor, after a drunken night of arguing with the girl's mother spiraled out of control.

According to court documents, Prassas, 36, is released on his own recognizance. Prassas teaches at Trevor Browne High School in the West Valley, but is on personal leave as a result of this incident.

Police say a woman and Prassas were too drunk to drive late Saturday evening, and that he had the woman's daughter get behind the wheel. In the backseat, police say the arguing escalated into Prassas striking the woman in the head and pulling her hair, forcing the teen to stop the car in a Peoria parking lot.

From there, court documents says Prassas pushed the teen down, injuring her.
